ABSTRACT As a fundamental and critical component of music information retrieval (MIR) systems, automatically classifying music by genre is a challenging problem. The traditional approaches which solely depending on low-level audio features may not be able to obtain satisfactory results. In recent years, the social tags have emerged as an important way to provide information about resources on the web. So, in this paper we propose a novel multi-modal music genre classification approach which uses the acoustic features and the social tags together for classifying music by genre. For the audio content-based classification, we design a new feature selection algorithm called IBFFS (Interaction Based Forward Feature Selection). This algorithm selects the features depending on the pre-computed rules which considering the interaction between the different features. In addition, we are interested in another aspect, that is how performing automatic music genre classification depending on the available tag data. Two classification methods based on the social tags (including music-tags and artist-tags) which crawled from website Last.fm are developed in our work: (1) we use the generative probabilistic model Latent Dirichlet Allocation (LDA) to analyze the music-tags. Then, we can obtain the probability of every tag belonging to each music genre. (2) The starting point of the second method is that music's artist is often associated with music genres more closely. Therefore, we can compute the similarity between the artist-tag vectors to infer which genre the music belongs to. At last, our experimental results demonstrate the benefit of our multi-modal music genre classification approach.
